Intel Announces Devil’s Canyon Core I7-4790K: 4GHz Base Clock, 4.4GHz Turbo

MojoKid (1002251) writes “Last year, Intel launched two new processor families based on the Haswell and Ivy Bridge-E based Core i7 architecture. Both chips were just incremental updates over their predecessors. Haswell may have delivered impressive gains in mobile, but it failed to impress on the desktop where it was only slightly faster than the chip it replaced. Enthusiasts weren’t terribly excited about either core but Intel is hoping its new Devil’s Canyon CPU, which launches today, will change that. The new chip is the Core i7-4790K and it packs several new features that should appeal to the enthusiast and overclocking markets. First, Intel has changed the thermal interface material from the paste it used in the last generation over to a new Next Generation Polymer Thermal Interface Material, or as Intel calls it, “NGPTIM.” Moving Haswell’s voltage regulator on-die proved to be a significant problem for overclockers since it caused dramatic heat buildup that was only exacerbated by higher clock speeds. Overclockers reported that removing Haswell’s lid could boost clock speeds by several hundred MHz. The other tweak to the Haswell core is a great many additional capacitors, which have been integrated to smooth power delivery at higher currents. This new chip gives Haswell a nice lift. If the overclocking headroom delivers on top of that, enthusiasts might be able to hit 4.7-4.8GHz on standard cooling.” Read more of this story at Slashdot.

Google To Spend $1 Billion On Fleet of Satellites

An anonymous reader writes “Google is planning to spend over $1 billion on a fleet of satellites to extend Internet access to unwired regions around the world. ‘The projected price ranges from about $1 billion to more than $3 billion, the people familiar with the project said, depending on the network’s final design and a later phase that could double the number of satellites. Based on past satellite ventures, costs could rise. Google’s project is the latest effort by a Silicon Valley company to extend Internet coverage from the sky to help its business on the ground. Google and Facebook Inc. are counting on new Internet users in underserved regions to boost revenue, and ultimately, earnings. “Google and Facebook are trying to figure out ways of reaching populations that thus far have been unreachable, ” said Susan Irwin, president of Irwin Communications Inc., a satellite-communications research firm. “Wired connectivity only goes so far and wireless cellular networks reach small areas. Satellites can gain much broader access.”‘” Read more of this story at Slashdot.

New Federal Database Will Track Americans’ Credit Ratings, Other Financial Info

schwit1 (797399) writes “As many as 227 million Americans may be compelled to disclose intimate details of their families and financial lives — including their Social Security numbers — in a new national database being assembled by two federal agencies. The Consumer Financial Protection Bureau posted an April 16 Federal Register notice of an expansion of their joint National Mortgage Database Program to include personally identifiable information that reveals actual users, a reversal of previously stated policy. The FHFA will manage the database and share it with CFPB. A CFPB internal planning document for 2013-17 describes the bureau as monitoring 95 percent of all mortgage transactions. FHFA officials claim the database is essential to conducting a monthly mortgage survey required by the Housing and Economic Recovery Act of 2008 and to help it prepare an annual report for Congress.” Read more of this story at Slashdot.

How LEDs Are Made

An anonymous reader writes “The SparkFun team took a tour of a factory in China that manufactures LEDs. They took lots of pictures showing the parts that go into the LEDs, the machines used to build them, and the people operating the machines. There’s a surprising amount of manual labor involved with making LEDs. Quoting: ‘As shipped on the paper sheets, the LED dies are too close together to manipulate. There is a mechanical machine … that spreads the dies out and sticks them to a film of weak adhesive. This film is suspended above the lead frames … Using a microscope, the worker manually aligns the die, and, with a pair of tweezers, pokes the die down into the lead frame. The adhesive in the lead frame wins (is more sticky), and the worker quickly moves to the next die. We were told they can align over 80 per minute or about 40, 000 per day.'” Read more of this story at Slashdot.

New Middleware Promises Dramatically Higher Speeds, Lower Power Draw For SSDs

mrspoonsi (2955715) writes “A breakthrough has been made in SSD technology that could mean drastic performance increases due to the overcoming of one of the major issues in the memory type. Currently, data cannot be directly overwritten onto the NAND chips used in the devices. Files must be written to a clean area of the drive whilst the old area is formatted. This eventually causes fragmented data and lowers the drive’s life and performance over time. However, a Japanese team at Chuo University have finally overcome the issue that is as old as the technology itself. Officially unveiled at the 2014 IEEE International Memory Workshop in Taipei, the researchers have written a brand new middleware for the drives that controls how the data is written to and stored on the device. Their new version utilizes what they call a ‘logical block address scrambler’ which effectively prevents data being written to a new ‘page’ on the device unless it is absolutely required. Instead, it is placed in a block to be erased and consolidated in the next sweep. This means significantly less behind-the-scenes file copying that results in increased performance from idle.” Read more of this story at Slashdot.

IT Pro Gets Prison Time For Sabotaging Ex-Employer’s System

itwbennett writes: “In June 2012, Ricky Joe Mitchell of Charleston, West Virginia, found out he was going to be fired from oil and gas company EnerVest and in response he decided to reset the company’s servers to their original factory settings. He also disabled cooling equipment for EnerVest’s systems and disabled a data-replication process. After pleading guilty in January, Mitchell has been sentenced to four years in federal prison.” Read more of this story at Slashdot.

Static Electricity Defies Simple Explanation

sciencehabit writes: “If you’ve ever wiggled a balloon against your hair, you know that rubbing together two different materials can generate static electricity. But rubbing bits of the same material can create static, too. Now, researchers have shot down a decades-old idea of how that same-stuff static comes about (study). ‘[The researchers] mixed grains of insulating zirconium dioxide-silicate with diameters of 251 micrometers and 326 micrometers and dropped them through a horizontal electric field, which pushed positively charged particles one way and negatively charged particles the other. They tracked tens of thousands of particles—by dropping an $85, 000 high-speed camera alongside them. Sure enough, the smaller ones tended to be charged negatively and the larger ones positively, each accumulating 2 million charges on average. Then the researchers probed whether those charges could come from electrons already trapped on the grains’ surfaces. They gently heated fresh grains to liberate the trapped electrons and let them “relax” back into less energetic states. As an electron undergoes such a transition, it emits a photon. So by counting photons, the researchers could tally the trapped electrons. “It’s pretty amazing to me that they count every electron on a particle, ” Shinbrot says. The tally showed that the beads start out with far too few trapped electrons to explain the static buildup, Jaeger says.'” Read more of this story at Slashdot.

Emory University SCCM Server Accidentally Reformats All Computers Campus-wide

acidradio writes: “Somehow the SCCM application and image deployment server at Emory University in Atlanta accidentally started to repartition, reformat then install a new image of Windows 7 onto all university-managed computers. By the time this was discovered the SCCM server had managed to repartition and reformat itself. This was likely an accident. But what if it weren’t? Could this have shed light on a possibly huge vulnerability in large enterprise organizations that rely heavily on automated software deployment packages like SCCM?” Read more of this story at Slashdot.

Your Old CD Collection Is Dying

Hugh Pickens DOT Com (2995471) writes “Adrienne LaFrance reports at the Atlantic that f you’ve tried listening to any of the old CDs lately from your carefully assembled collection from the 1980’s or 1990’s you may have noticed that many of them won’t play won’t play. ‘While most of the studio-manufactured albums I bought still play, there’s really no telling how much longer they will. My once-treasured CD collection — so carefully assembled over the course of about a decade beginning in 1994 — isn’t just aging; it’s dying. And so is yours.’ Fenella France, chief of preservation research and testing at the Library of Congress is trying to figure out how CDs age so that we can better understand how to save them. But it’s a tricky business, in large part because manufacturers have changed their processes over the years and even CDs made by the same company in the same year and wrapped in identical packaging might have totally different lifespans. ‘We’re trying to predict, in terms of collections, which of the types of CDs are the discs most at risk, ‘ says France. ‘The problem is, different manufacturers have different formulations so it’s quite complex in trying to figure out what exactly is happening because they’ve changed the formulation along the way and it’s proprietary information.’ There are all kinds of forces that accelerate CD aging in real time. Eventually, many discs show signs of edge rot, which happens as oxygen seeps through a disc’s layers. Some CDs begin a deterioration process called bronzing, which is corrosion that worsens with exposure to various pollutants. The lasers in devices used to burn or even play a CD can also affect its longevity. ‘The ubiquity of a once dominant media is again receding. Like most of the technology we leave behind, CDs are are being forgotten slowly, ‘ concludes LaFrance. ‘We stop using old formats little by little. They stop working. We stop replacing them. And, before long, they’re gone.'” You can donate CDs to be tested for aging characteristics by emailing the Center for the Library’s Analytical Science Samples. I haven’t had much trouble ripping discs that were pressed in the 80s (and acquired from used CD stores with who knows how many previous owners), but I’m starting to get nervous about not having flac rips of most of my discs.
